verilog 设计流水灯

Verilog HDL 数字设计与综合，夏宇闻译。本书重点关注如何应用verilog语言进行数字电路和系统的设计和验证，不仅讲解语法，更从基本概念讲起，逐渐过渡到编程语言接口以及逻辑综合等高级主题。(The design and synthesis of Verilog HDL digital, Xia Wen translation. The book focused on how to apply the verilog language for the design and verification of digital circuits and systems, not only explain the grammar, the more I start from the basic concept, and a gradual transition to advanced topics such as programming language interface and logic synthesis.)

用DE0开发板实现电话计费器，基本功能：可设置通话模式，能初始化话费余额，拨动开关可进入通话模式，并根据通话时间和相应通话模式扣除相应的费用。通话过程中能够通过开关切换显示通话时间和话费余额，并可暂停通话。压缩包里有详细的WORD文档的说明，包括波形仿真和DE0的引脚功能介绍。(Implemented by DE0 board telephone billing, basic function: to set the call mode, you can initiate credit balance, toggle switch into the talk mode, and deduct the cost of a call based on call time and the corresponding mode. Call talk time and can be displayed by switching credit balance, and mute. Compression bag has a detailed description of WORD documents, including the waveform simulation and DE0 pin function description.)

VHDL implementation using mouse and monitor

双时钟域FIFO(This is self-defined Dual-Clock FIFO, using logic lut resources. Dual-Clock FIFO, Depth: 256 Width: 32 USEDW: Y FULLL:Y EMPTY:Y)

资源描述 说明： 结绳模块(Pluse2Toggle): 负责延长待采样信号 同步模块(Synchronization)：负责双触发器锁存 解绳模块(Toggle2Pluse)： 负责将长信号转换成脉冲信号 支持信号从快时钟域到慢时钟域，也支持信号从满时钟域到快时钟域，

使用verilog语言完成了基于cordic算法求反正切的计算，精度为8次迭代(Verilog language used to complete based on CORDIC algorithm for arctangent calculation, an accuracy of 8 iterations)

文档包括双线性插值算法和最近邻域算法的详细介绍，以及算法的相关计算。(Documentation includes bilinear interpolation algorithm and the nearest neighbor algorithm which is described in detail, as well as algorithms related calculations.)

自编同步串口收发，单端信号可实现板内，配合422或LVDS板间传输效果不错内附pingpang缓存接受的例程，帮助快速构建代码，FIFO请根据器件生成或自编

该程序实现最小频移键控信号的调制解调，经测试无误。(The program implements minimum shift keying signal modulation and demodulation, tested and correct.)

用VHDL和verilog编写的RGB颜色空间到YUV颜色空间的转换程序, 是FPGA视频处理中的常用程序!(Written in VHDL and verilog using RGB color space to YUV color space conversion process is commonly used in video processing FPGA program!)
